SECTION 2.0: NETWORK IMPLEMENTATION STRATEGIES
2.1 IMPLEMENTATION STRATEGIES
Monitoring
Several D-100 parameters are available for monitoring purposes. These include Volume Rate
(Point 4), Ai3 - Generic Analog Input 1 (Point 5), and Ai4 - Generic Analog Input 2 (Ppoint 6).
These points can be unbundled for use in trending the performance of the hydronic system or
used in various global control strategies.
Totalization
Three D-100-P1 Display parameters are available for accumulating totalized data. These are Mode
1 Volume Total (Points 11 & 12), Mode 2 Volume Total (Points 15 & 16) and (optional) auxiliary
input (Points 17 & 18). Typically the Mode 1 and Mode 2 Volume Total points of the D-100-P1
Display are used to quantify the amount of water consumed in custody transfer applications.
They may also be used to accumulate total consumption for use in ongoing plant or system
efficiency measurements.
D-100-P1 Display totalization registers are 7 digit registers. User defined units and multipliers
are then applied to these values. This is required to allow for the accumulation of totals over a
reasonable time period without exceeding the capacity of the reigster. P1 variables are limited
in range to 32,767. In order to properly convey the D-100 information, each totalization register
is represented by two separate type 3 LAI points. The first point represents digits from 0 - 9,999.
The second point represents the digits from 10,000 to 9,999,999. The user-selected multiplier is
applied to the units for the first word. For the second point, the multiplier is adjusted by a factor
of 10,000, then applied to the units.
Multipliers
ONICON D-100 Volume Rate and Accumulation Points have multipliers. Multipliers are 1, 10,
100, 1,000, 10,000, 100,000 or 1,000,000. For points 11, 12, 15, 16, 17, and 18 the point descriptor
will contain the multiplier. The 11 multipliers are as follows:
